I borrowed that from capitvhach (hope you don't mind!) because it is exactly what mine is doing. It won't do it in 2wd with hubs locked or unlocked, it only makes the should when using 4wd. I need a new exhaust, I removed my stacks and the 90* up to the bed behind the cab is now turned out in front of the wheel. I can't hear much ha. But I can hear this!

What should I look into? thanks!

Na man i dont mind still looking here myself. I pulled the wheel bearing and greased it. Not it I pulled front driveshaft and my pinion is tight. Front cover was off all gears and pinion looked good. Kinda sounds like a dry bearing roar. Hopefully gonna go to the rack mon/tues to try to listen. My creeper got shacky at 12mph trying to ride under the truck and listen (jk)

Idunno if this will ever go away, it could be just the backlash your hearing in the diff, mine does this too and i completely rebuilt the front end, minus the diff, and the noise is still there..it hasnt hurt anything yet and until it does i just ignore it..

man, that's not good to hear. I was going to try new hubs, it seems like that would be it!
My truck just started to do it, unless I just didn't hear it in the past.
